摘要
本文介绍了一套用于宽幅胶片生产线整理工序的弊病在线检测系统,该系统用来实时检测胶片表面常见的弊病。系统采用2台线阵CCD摄像机同步成像,940nm的LED面阵光源提供照明,利用单行处理、多行判断的快速弊病检测算法及时发现弊病。现场运行结果表明,系统能够完成对运行速度为90m/min,宽幅为1300mm的胶片表面弊病的检测任务。
An on-line inspection system was developed for wide film （width： 1 300 mm） production, which is able to detect the defects on the film surface. The system consists of two sets of 8 Kpixel high-resolution linear CCI） cameras and an infrared illumination source with 940 nm LED. Then the images captured by two cameras are processed synchronously using single line processing and multiple lines judgment algorithm. Field operation shows that running at a high speed of 90 m/min, the system is able to detect the surface defects of wide film with the width of 1 300 mm in real time and operates normally.
